Man of Honour
I have no idea what new slr id get im still learning my 400DBUT id move to Nikon if i had the chance
Brave move, the D7000 will be a good camera I'm sure but the move between the systems is annoying, the philosophy behind the control systems is different, let alone the layout of the controls themselves...if you only use one you'll probably adjust with a bit of time but swapping between the two during a day's shooting is a mental challenge.
BUT id move to Nikon if i had the chance
